UNITED STATES ROBERT HENRY IvCHIGI', 0F Ifi-NBY, ONTARIO, CANADA BAG nGLDER Application filed Marck 8, 1929. 'Serial No. 345,342.

This invention relates to the broad class of bag holders and it has more particular reference to that species which embodies a wheeled portable truck or carrier, and an associated bag holding device mounted thereon.

The purpose of the invention is to provide More specifically stated, have evolved.

and produced a structure which is characterized by a combined portable truck and bag holder having improved bag-mounting means which may be moved longitudinally of the truck to support bags of various lengths, and which is adjustable laterally with respect to the side bars of the truck to support bags of different sizes.

One feature of the invention is the provision of a novel slidable frame which is longitudinally adjustable on the side bars of the truck, which constitutes an appropriate mount-ing for a special bag-clamping device, and which is associated with dependable retaining means for holding it in different adjnsting positions to accommodate bags of different lengths.

An equally important feature of the invention is the bag-retaining or clamping unit, which is disposed at right angles to the slidable frame and which is separa-bly connected therewith and provided with novel cooperating elements to enable a single person to 4,) Vplace the mouth of the bag in position thereon, whereby to hold the `mouth open for unhampered reception of the contents.

Other features and advantages of the invent-ion will become` more readily apparent from the following description and drawings.

In the drawings:

Figure 1 is aside elevational view of the compound structure showing the truck, the right angularly disposed bag clamp and the bag in dotted lines;

Figure 6 is a View similar to Figure 5 o bserving the opposite` side of the bag-clamping means and showing the lstructure in elevation. l

te will first analyze the structural details of the portableV truck 7. This truck is provided with appropriate wheels 8 and with spaced parallel tubular side bars 9 terminating in appropriate curved handles 10. There is a reinforcing cross bracell adjacent the n handle. Then at the bottom there is a. foot plate 12 of the curved configuration shown in Figure 1, said plate serving to hold the truck ina vertical position as here represented. Extending transversely of the side bars 9 and rigidly connected thereto just below the brace 11 is a cross piece 13 with which a longitudinal bar 1451s connected. The lower'end of this bar is fastened to the foot piate 12 and one edge of the bar is is slidably engageable with one edge of the rack bar 14. Moreover, the bar 17 carries a pivoted operating lever 21 for a retaining pawl 22'which cooperates with the teeth 15 and serves to hold the frame in different adjusted positions to accommodate bags of f dierent lengths. At this time I invite attention to Figure 2 wherein it Will be observed that the reference character 23 designates a small plate which is'riveted .to the cross bar 17 and which is provided with a ywith the abutment plates 23.

slot. There are two of these plates 23 as seen in Figure 2 and they operate as abutments for stop plates for cooperation with the bagsclamping unit or device, In this connection it will be evident that the bagclamping device. is detachably connected with these plates and is therefore adjustable in unison with the sliding frame.

rlhe bag-clamping device, generally considered, is ot substantially U-shaped form as seen in Figure 4. The bight or connecting portion 24 is in the form of a U-tube and this is provided with longitudinally spaced bag hooks 25. In addition attaching plates 26 are rigidly connected with this tube and the plates are formed with retaining hooks 27 as shown in Figures 5 and G for engagement In addition these plates are provided with down-turned reinforcing flanges 28 and formed on their under sides with block-like abutment pieces 29 which bear against the abutment plates 23 to hold the complete device in substantially horizont-al position and at right angles to the sliding trame. Associated with the laterally directed end portions of the tube 24 are individual spring pressed bag-engaging devices 30 and 3l respectively (see Fig. 4) ,these being adapted to be engaged with the torward corner portions of the bag 32. Al-v though these devices are substantially the saine in general construction, they are difierentiated by the reference characters 30 and 3l because ot the fact that theyare successively operable in order to permit a single person to place the bag in position. For instance, the device 30 is ot a quick releasable type while the device 3l is ot a retarded releasable type. In tact the device 31 may be held in retracted position while the adjacent corner ot the bag is slipped thereover while the device 30 may be momentarily retracted and then released for quick engagement with this pa ticular corner ot the bag. Because ot this distinction in construction I invite attention to Figure 5 first.L This shows the device 3l.. As seen here the reference character 33 designates a'rod titting'telescopicaily but rigidly into the adjacent end of the tube 24. The outer end of this rod has its upper half cut away as at 34 to provide a reduced extension and the bag-engaging device 35 is slidably mounted on this. The bag-'engaging device is formed from a shortlength of pipe including a tubular portion'36 slidable on the part 34 of the rod and a flattened bag-engaging head 37 engageable with the iiat `surface of the eX- t'ension 34 to prevent turning of this part 35 on the rod 33. In addition there is a coil eX- pansion spring 38 ior forcing the device 35 normally outward to engage the corner ot the bag. In addition,- inanually manipulated means is provided tor i'novin-gthis device iinvardl'y against they tension of the spring. The, `i'i'n'ea'is comprises a small leye'r 39 having a pivotally mounted disk-like portion 40 carrying an eccentric pin 4l. A link 42 has one end connected with this pin and the opposite end connected with a lug 43 on the device 35. rih'is lever 39 may be pulled down and swung around in a direction from left to right in Figure 5 whereby to cause the eccentric pin 4l to exert a longitudinal pull o-n the link 42 and to move the link from the full line position to the dotted line position. The eccentric pin, passing beyond dead center, serves to hold the lever 39 in this position and to maintain the device 35 retracted against the tension of its complemental spring 34. rIhis is the retarded action before mentioned. In other words, it is desirable in order to permit a single. person to use this device to be able to hold the part 35 in retracted position for a time to facilitate placement of the bag.

ri`he complemental device 44 on the opposite side is similar in construction but slightly different in action. Referring to Figure G it will be seen that it comprises a flat head 45 and a tubular portion 46 equipped with a lug 47 with which-a link 48 is connected. In addition there is a rod 49 fitting telescopically into the adjacent end of the tube 24, and an expansion spring 50. In this instance the lever includes a pivotally mounted disk-like portion 52 having a per'pheral extension 53 provided with a pin 54 with which the opposite end of the link is engageable. This lever is movable upwardly toward the bagengaging device; that is, it is movable to the 1 dott-ed line position here shown. Thus by placing the hand beneath the lever and lifting upwardly on it, a pull is exerted upon the link 48 to move the link to the dotted line position here shown. This momentarily retracts the device 44, but as soon as the lever is released, the spring comes into play for returning the device 44 and quickly engaging the adjacent portion of the mouth of the bag.

Particularly, doV I wish to emphasize the construction of the bag holder comprising the attaching plate separably connected with the abutment plates on the sliding frame, and the construction wherein stationary hooks 25 are provided on the tube 24, and successively operable spring-pressed devices 30 and 3l are provided., and so operable as to permit a single person to readily slip the corners of the mouth ot the bag over the respective parts 35 and 44 in the manner described.

It is Vbelieved that by carefully considering the description in conjunction with the drawings, a clear understanding 0I" the construction, operation and advantages of the invention will be had. Therefore, a more lengthy description is regarded unnecessary.

Mino-r changes in shape, size, materials and rearrangement ot. details coming within the lield ot the invention claimed may be res rted to in actual practice if desired.
